  • Birefringent Strands in Polymer Flows in a Co rotating Two

    Birefringent Strands in Polymer Flows in a Co rotating Two

    We study flow of polymer solutions in a co-rotating two-roll mill. Polymer molecules are significantly extended downstream of an isolated stagnation point in the nip, creating a birefringent strand visible through optical experiments.roll crusher Dealer, Fote. The elastic stress created by the strand is approximated by a line of discontinuity in shear stress. Since the height of the nip is small in …
